==Key Stage 4==
===Meaning===
[[File:HeaterSymbol.png|right|300px|thumb|The symbol for an '''electrical heater'''.]]
A '''heater''' is a [[Electrical Component|component]] in a [[circuit]] which is [[heated]] when a [[Electrical Current|current]] goes through it.
===About Electrical Heaters===
: '''Heaters''' are usually long lengths of [[wire]] which a high [[Electrical Resistance|resistance]].
: As a [[Electrical Current|current]] passes through a [[wire]] [[electron]]s in the [[Electrical Current|current]] [[collide]] with [[ion]]s in the [[metal]] [[lattice]] causing them to [[vibrate]]. This increases the [[temperature]] of the [[wire]].
